Answer:
20%
Step-by-step explanation:
To find the percent increase lets first find the increase.
36-30 = 6
Now divide the increase by the original amount
6/30 = 1/5 = 20%
The answer would be
- (34x^3 - 35)
The y-intercept would be (0,8) because the last number on the equation, aka the c value, is you y-intercept.
